Tinea corporis (also known as ringworm,[1] tinea circinata,[2] and tinea glabrosa[1]) is a superficial fungal infection (dermatophytosis) of the arms and legs, especially on glabrous skin; however, it may occur on any part of the body.

Signs and symptoms

It may have a variety of appearances; most easily identifiable are the enlarging raised red rings with a central area of clearing (ringworm).[3] The same appearances of ringworm may also occur on the scalp (tinea capitis), beard area (tinea barbae) or the groin (tinea cruris, known as jock itch or dhobi itch).

Other classic features of tinea corporis include:

  • The edge of the rash appears elevated and is scaly to touch.
  • Sometimes the skin surrounding the rash may be dry and flaky.
  • Almost invariably, there will be hair loss in areas of the infection.[4]


Tinea corporis is caused by a tiny fungus known as infection.[5]

The disease can also be acquired by person-to-person transfer usually via direct skin contact with an infected individual.[3] Animal-to-human transmission is also common. Ringworm commonly occurs on pets (dogs, cats) and the fungus can be acquired while petting or grooming an animal. Ringworm can also be acquired from other animals such as horses, pigs, ferrets and cows. The fungus can also be spread by touching inanimate objects like personal care products, bed linen, combs, athletic gear, or hair brushes contaminated by an affected person.[3]

Individuals at high risk of acquiring ringworm include those who:


Superficial scraps of skin examined underneath a microscope may reveal the presence of a fungus. If the skin scrapings are negative and a fungus is still suspected, the scrapings are sent for culture. Because the fungus grows slowly, the culture results do take several days to become positive. Other methods of diagnosis include potassium hydroxide (KOH) tests.


Because fungi prefer warm, moist environments, preventing ringworm involves keeping skin dry and avoiding contact with infectious material. Basic prevention measures include:

  • Washing hands after handling animals, soil, and plants.
  • Avoiding touching characteristic lesions on other people.
  • Wearing loose-fitting clothing.
  • Practicing good hygiene when participating in sports that involve physical contact with other people.[5]


Most cases are treated by application of topical antifungal creams to the skin, but in extensive or difficult to treat cases systemic treatment with oral medication may be required. The over-the-counter options include tolnaftate.

Among the available prescription drugs, the evidence is best for terbinafine and naftifine, but other agents may also work.[6]

Topical antifungals are applied to the lesion twice a day for at least 3 weeks. The lesion usually resolves within 2 weeks, but therapy should be continued for another week to ensure the fungus is completely eradicated. If there are several ringworm lesions, the lesions are extensive, complications such as secondary infection exist, or the patient is immunocompromised, oral antifungal medications can be used. Oral medications are taken once a day for 7 days and result in higher clinical cure rates. The antifungal medications most commonly used are itraconazole and terbinafine.[5][7]

The benefits of the use of topical steroids in addition to an antifungal is unclear.[6] There might be a greater cure rate but no guidelines currently recommend its addition.[6] The effect of Whitfield's ointment is also unclear.[6]


Tinea corporis is moderately contagious and can affect both humans and pets. If a person acquires it, the proper measures must be taken to prevent it from spreading. Young children in particular should be educated about the infection and preventive measures: avoid skin to skin contact with infected persons and animals, wear clothing that allows the skin to breathe, and don't share towels, clothing or combs with others. If pets are kept in the household or premises, they should get the animal checked for tinea,[8] especially if hair loss in patches is noticed or the pet is scratching excessively. The majority of people who have acquired tinea know how uncomfortable the infection can be. However, the fungus can easily be treated and prevented in individuals with a healthy immune system.[4][7]

Society and culture

When the dermatophytic infection presents in wrestlers, with skin lesions typically found on the head, neck, and arms it is sometimes called tinea corporis gladiatorum.[1][9]
